How Mecha focused will this be? I've not done one before as they are generally not my thing. Is it going to be small one-time instances of YETI use? or will they be the major focus of the combat scenes?

It's going to be a mix of espionage, combat, and general action/adventure. There will be YETI battles, but not all the time.
