CFI training
Are you at a school and/or did you get your CFI from a school? Use the syllabus from one or the other or both. Maybe you have a colleague or bud(s) who got their CFI(s) from a school and will let you borrow their course materials.
In any event, get the CFI PTS. You can create a course around that. After all, the PTS IS the test. The PTS will refer to standard FAA materials which your student will be expected to know.
You will spend most of your time at the beginning drilling your student on the FOI. You, and every CFI, should know the FOI cold. Then, later, you will become the "student" as your trainee teaches you the maneuvers. You will spend a good amount of time oralling your student and critiquing his/her presentation.
For flying, first let your student get comfortable with flying out of the right seat. I'd suggest that you practice landings on EVERY flight. After your student is comfortable flying from the right seat, start working on the Private and Commercial maneuvers.
Emphasize to your student that while flying that he/and she must talk up everything he/she is doing at every moment. Your student should never stop teaching.
Hope this helps. What is neat about training a CFI student is you will get surprisingly good refresher training and be paid for it.
