It depends what level you are (and hence what spells you have available). Basically it's pull with Avengers shield, fire up Holy shield, then judge crusador on the mob and start hitting them with Seal of Rightousness.
There are variationss depending on what you are pulling (you can pull demons and undead with Exorcism, this is especially good if you have a hunter trapping other mobs as you don't build aggro on them so the hunter can get their attention easier).
Reconning is a great talent to have while leveling, but once you hit 70 you want to put those 5 points elsewhere, you won't be getting hit often enough to make it's procs worthwhile and the 5 points can be better spent in other talents.
You definatly want to pickup 1-handed weapon specialisation as this ups all of your damage, so you can hold mobs on you easier. Get yourself a good spelldamage sword, and don't worry about the white dps that it does, white dps is completly unimportant for a tankadin as all of you aggro comes from your opening spell (avengers shield) and your reflective spelldamage when things hit you.
