First take a look at this Gold Guide for some of the best gold making information out there, if you are low on gold that is.
There are minor things that change from tank to tank so there isn't a standard "These are the best enchants for a tank" it's really dependent on the tanking class as you will see if you compare these enchants to the Death Knight enchants. Some stats are just more important than others depending on the tank.
This guide will cover what the best enchants for your Warrior by slot. This guide assumes that you are defense capped at 540 defense, if you are not, then you may want to take any defense enchants that may have not made their way to the #1 slot.
Please keep in mind that some things in this guide are only for specific professions, they are labeled so there is no confusion. This guide covers not only enchants but everything that is considered an item enhancement.
Back
Most tanks go for the defense enchant here with Titanweave and they are wrong to do so. For Warriors especially the +22 agility is better, and even better than that is the +225 armor.
Mighty Armor - +225 Armor
Flexweave Underlay (Engineer only 380 skill) +23 Agility
Major Agility - +22 Agility
Titanweave - +16 defense
Dodge - +12 Dodge
Threat
Haste +23 Haste Rating
Swordguard Embroidery (Tailors only, 420 skill) Chance to get 400 attack power for 15 seconds
Chest
A common misconception here is that +10 to all stats is the best tanking enchant for chest, it's not, it's not even the 2nd best, of course, all this is dependent on what you are using the tanking stats for. On a general scale these are the best in order.

Hands
Generally most Tanks will take the Armsman enchant as it provides a good threat boost and some defensive mitigation, if you don't need to worry about threat, then the Glove Reinforcements are the next in line best tanking enhancement for gloves. Most tanks miss this and go for stamina instead.

Blade Ward is by far the best tanking enchant for the warrior, but if you can't afford it or want to do something different, there are more options.
Blade Ward - +200 parry, 600-800dmg on next parry
Mongoose - +120 agility, +attack speed
Blood Draining - Restores 360-440 Health, stacks up to 5 times when below 35% health

Threat

Shield
Most warriors make the mistake in thinking +20 Defense or stamina is better for them here, but Block Rating is extremely important for a Warrior, unless you're going to be using the major stamina for caster fights, the Titanium Plating is 2x better or more than the other enchants.
