For a tournament game you need to break down your game into component parts. I personally either use mind mapping software or just do it with a bunch of little circles on a scratch paper to start.
Feet - Offense/Defense - what are your best throws, takedowns, etc? how can you defend the most 5 common throws in tournament BJJ? What stance will you use - regular or southpaw? Do you practice pulling guard in randori if that's one of your strategies?
I like to think not of individual techniques here, but of pathways. What are your pathways in top game? (Ex: Takedown, knee step-over to half guard, knee cutter pass to side control, lapel free feed under head, knee-on-belly, lapel choke or far side armbar). If you don't have a pathway, then start to figure out what your high percentage pathways are. Hint: you can string a few of your stronger techniques together to form your primary pathways.
What are your pathways here? What type of guard? What guard transitions? (Ex: Guard pull, closed guard, collar sleeve grip, angle off to armbar/triangle/omoplata/reversal)
What's your grip fighting strategy? Front hand collar grip first, step in follow? Back hand sleeve to front hand collar?
Rolling Prep Strategy
What's your strategy for building your game while rolling? (Ex: Primary 3 pathways MWF, TTh new technique plus problem positions).
As you can see most of this is breaking it down into smaller bite-sized pieces and putting together a plan for improving each piece and getting them to flow together.
