There isn’t a list of ingredients you have to have in a playbook.
A typical, complex American Football playbook has these sections:
Objectives for the playbook (“suitable for kids 10-12”
“Concepts” to be discussed with coaching staff
Terminology
Landmarks on the field of play
Player positions with names and requirements
Formations and numbering of players, holes, ball-carriers, defenders
Personnel sets and their designated signal
Routes to run, with names, description, adjustments
Plays
Series of plays and movements, often as diagrams for various formations
Rules and instructions for every player from every formation for every play
Protection schemes and their names, descriptions, and adjustments
Play signals and cues, coaching points
Audibles and variations
Possible combinations of all the above
There are many examples on the internet. You can even find (old) playbooks from professional teams.
If you look at some of them, you realize how much teaching and learning has to happen for coaches and players. To use all the plays to their full intent takes time and practice!
My template is a lot simpler. It starts with the Tactical Model and explains some essential concepts. Then it lists a very limited number of plays. Each play includes graphics containing only essential information. Two thirds of its pages are actually filled with installation plans. Those are details for practicing, and activities and drills for learning the plays.
