You can also just look at already-existing unique faction units and scour through the tables for their restrictions and permissions.
Of course, that's a lot of work if all you want is just a small mod that makes all your units twice (or half) as strong as the AI's. Unfortunately, without clever scripting or abuse of certain game mechanics, this is the only way.
This goes likewise for technologies and buildings - you'll need to create a separate tech tree somehow, and again somehow make this tree available only to one faction (I don't even know if that's possible), and unique faction versions of each building.
Even with all that, it is only for the faction, not the player. Thus, if the player is playing another faction, then that AI faction does get all those changes.
