We will tackle the disciplines the same way we tackled the domains. Each set will have a name.
We will use the powers from 3rd edition and supplement with new ones we feel we need, added in from 2nd edition or brand new (although I want to avoid that as much as possible).
Here is one example:
Third Eye Psionic Discipline
This discipline grants you the ability to open a third eye within your mind, allowing you to perceive things
that others miss.
Concentration: While concentrating on this discipline, you have blindsight with a radius of 10 feet.
Tremorsense (1): As a swift action, you gain tremorsense with a radius of 30 feet for 1 minute.
Unwavering Eye (1): As a swift action, you gain a +4 competency bonus on Wisdom checks (including saves and skills) for 1 minute.
Ubiquitous Vision (3): You have all-around vision.
