That depends. I have two tanks and they both have their attribute points spread out differently. My Nightblade Sap Tank (Siphons-Shadows) is mostly specced into Health, but he also has points in Magicka. I don't believe he has any points into Stamina. My second tank, Aerinon the Blaze, is a Templar Blazing Shield tank, which means he is a high health tank. He doesn't have any points into health; instead, he gets most of it from the Plague Doctor set and enchants.
As far as actually making a tank, they have the most viable options out of all the roles. Any class and any race can be a tank, but if you want to make the "perfect" tank, then your best bet is going Dragonknight, and either a Nord, Orc, or Imperial. You should be wearing 5 pieces of heavy armor at minimum, but I prefer to wear full 7 heavy for the passives. Both bars are generally going to be equipped with a one handed weapon and a shield.
For gear sets, tanks can get good use out of more sets than any other role, but there are a few you might want to gather anyway. The Ebon set drops from Crypt of Hearts I and II, and it provides a health boost to your group mates that can be useful in Trials. Tanks might also use Alkosh, which drops from the Trial Maw of Lorkhaj. Other sets, like Hist Bark (which is craftable) can be used as well. It just depends on exactly what you want your tank to be doing.
Exactly what traits your gear has also depend on what you want to be using. I typically run Infused on the three big body pieces (head, chest, legs), reinforced on the pieces that grant more protection (especially the shield, which will be the piece with your highest armor rating with a certain CP passive), and sturdy on the pieces that grant the least protection (like the waist). The reason I run Infused on the larger pieces is to get a boost from my enchants, and I run the Hakeijo enchant on both of my tanks (Hakeijo provides a boost to health, magicka, and stamina, though it's less of a boost than a single Deni, Makko, or Oko).
The goal for health should be 30k with a purple quality food (one that boosts the three stats), but max stamina and magicka tend to vary on whether or not your tanks focus is mostly stamina skills or magicka skills. A DK tank will probably want more stamina. Magicka regen is more important than health or stamina regen, since you'll be relying mostly on your healer to heal you in groups (though you should be able to survive for a while without one), and you don't regen stamina while blocking. I run magicka regen glyphs on all my jewelry, and I use the Atronach stone to further boost the regen. Some people might run block cost reduction glyphs on their jewelry, but I haven't found that necessary.
For Champion Points, my tanks are actually specced similarly to my magicka DPS characters. The only real difference is where I put my Thief points. For those, I put around 80-85 points into the magicka cost reduction and regen stars, and the rest are split with 10 or so in roll dodge cost reduction and 20-30 in block cost reduction. This will probably change depending on what CP changes are coming with Morrowind.
As for skills... A Dragonknight has the most tank-like skills available to use. The absolute requirements for a tank are a taunt. The one hand and shield skill Puncture, morphed into Pierce Armor, is the preferred one. However, there are some fights where having a ranged taunt (Inner Fire from the Undaunted skill line) is required, the primary example for that being the second boss in Maw of Lorkhaj. Now, as a tank, your primary job is the hold boss aggro, control fights, and buff/debuff things. Dragonknights have the most utility for this sort of scenario. You'll want to consider getting Igneous Weapons, Chains, Talons, Green Dragon Blood, and probably several other skills that I'm forgetting about. I don't run DK tanks, so I can't provide any advice on that point. I can only say, however, that you may wish to go into Cyrodiil to unlock Warhorn. It requires Assault rank 4 to get, which doesn't take long to get to these days. I unlocked it on one of my tanks mainly through repairing keep walls. Once that's morphed to Aggressive Horn, it provides a nice crit bonus that helps with group DPS.
If you're not running Warhorn, though, then you might want to consider getting the one hand and shield ultimate, which can be useful in certain fights (like Velidreth, in Cradle of Shadows).
That's pretty much all I can think of off the top of my head. I really can't provide much help with Dragonknight tanking, but I do know my Sap Tank and my Blazing Shield tank.
