Really though, there should be an overall briefing. There are numerous guides out there. Things that should be covered are division of duties, normal procedures, control changes, deviations from parameters, and other factors.
There also should be a briefing before the initial takeoff including speeds, abort points/speeds, configuration, emergencies.
Each approach will need its own briefing including things such as the weather, navaids, timing (if required), radios and other cockpit setup, then the actual approach including fixes, altitudes, step-down points, missed approach procedures, control change (or not) at the bottom.
You should find something suitable for the aircraft in question and practice it using actual approach plates and actual planning numbers until you understand it and can reel it off easily.
