What's a good gift for a dad? I'm always lost on what I should give.

I gave my dad a watch for Father's day. He loved it not just because of the design or any other aspects but also for the reason that it was from her daughter. So I suggest, pick something that best describes what your dad wants and he will surely be happy whatever it is. That's the simplicity I like about dads.
