Being a son is simply about being. It's the father that has a lot to do in the relationship. The only thing I'd say is to be patient and try to be understanding. Besides that, it's up to him.

Good luck.

Edit: sorry, I just skimmed it the first time. Sounds like your dad doesn't understand that it's his responsibility to respect his wife, your mother. If you're interested in speaking to him, sit him down and give him a man to man. "Dad, if you have something to say to mom or I, say it to our faces. If you see something that needs to be done around the house, then man up and do it. I don't want to see any more of this passive aggressive behavior anymore."
