For the Discipline tree, this is the best build that I have found and used so far for patch 4.1 with my priest. This build utilizes Archangel and Atonement so pay close attention to what those talents do before you try out this build for yourself.
Here’s a list of the spells you’ll gain by using this build and what they do:
Archangel – Consumes your Evangelism effects, causing an effect depending on what type of Evangelism effect is consumed.
Inner Focus – Reduces the mana cost of your next Flash Heal, Binding Heal, Greater Heal, or Prayer of Healing by 100% and increases its critical effect chance by 25%.
Power Infusion – Infuses the target with power, increasing spell casting speed by 20% and reducing the mana cost of all spells by 20%. Lasts 15 sec.
Pain Suppression – Instantly reduces a friendly target’s threat by 5%, and reduces all damage they take by 40% for 8 sec.
Power Word: Barrier – Summons a holy barrier on the target location that reduces all damage done to friendly targets by 25%. While within the barrier, spellcasting will not be interrupted by damage. The barrier lasts for 10 sec.

Again, if you are unfamiliar with playing a Discipline Priest be sure to review all of your talents before starting so you know what you are getting yourself into!
