Good advice from JNB. Make your own lesson plans, without going into too much explanation, you will be glad you did. Also write them on a program like MS Word. This also helps when you make slight changes to them. Also add notes and points of emphasis. Also incorporate power settings, configurations, and "gotchas" Etc. If you put some though into the lesson plans they will be complete, comprehensive yet easily workable and not complicated or cluttered. Remember this is not just about getting your CFI, you owe it to your student and others to do the very best possible. Also don't forget the principle of primacy and like JNB said "Telling is not teaching" as far as items that you think might not be in the PTS, many actually are, though may not be referenced directly. It is safe to say you should also be able to teach how to tie down an airplane, so you should be able to teach a knot or two. There is lots of little stuff like that. Make lesson plans for those things as well. After you think your plans are finished and your instructor critiques them, start practice teaching. Do it at home, teach your mate, your kids, your pets if you have to. Practice, Practice, Practice! and Talk, Talk, Talk! Practice in much the same way a salesman does, A good salesman takes a complicated script and practices until it flows, until they are comfortable and it is conversational. And like a good salesman, stick to the script/follow the format. Especially when a new CFI, you don't have enough experience to wander into uncharted territory, that will cause big problems. If you don't know the answer to something, do not make one up! Tell your student "I don't know, but we will find out" or look it up, Etc.
