your dad stands on your right, but he sits on the left side with your family.
If you wear the veil over your face, right before your dad sits down, he can lift it and give you a kiss on the cheek. Traditionally he would put it down again and then the groom would lift it later on. But if you didn't want it over your face during the ceremony you could just not put it back down.
Then when you're standing up there you just turn and hand your MOH the bouquet. But if you forget, I'm sure the officiant will signal you to do it, just like a pp said.
Hope that helps!
