A locket would be a lovely idea. I have no doubt your father would be thrilled.
Do you have the photograph already? If he's as experienced as I believe him to be, your portrait should be of appropriate locket sizing. All you would have to do is cut out your face.
The design is what requires great thought... You are known to have a wolf motif, so perhaps an engraving of a wolf's head to remind him of you even when the locket is closed. Initials are another option, and could serve as interest for the back.
