There really is very little you can do to prepare. You don't have the burden of proof here. The employer does. They have to present evidence that you committed some act of misconduct that can block your unemployment. If they allege a minor act, they have to also prove that you had been warned against that misconduct and still did it anyway.
This will require something very specific from the employer. They can't just say that you didn't work out or that you didn't do as you were told. Those are performance issues and even if they can prove them, those do not rise to the level of misconduct.
All you have to do is respond to the fact finding letter concerning the circumstances of termination, and then wait to see what the employer says. You'll be given the chance to rebut their evidence. Unfortunately, until you see what they present, there is no way to prepare.
