Invite him to read a text or a wish.
You can do it more personal by choosing a text that is important for both of you. It may be a quote from the book he used to read when you were a child (love the popular quote that sounds at weddings from the book The Velveteen Rabbit), or a prayer or poem associated with the love of a father.
Draw a separate first dance with him.
While the father-bride dance is granted, you can make more special by making some months dance lessons before marriage, or choreographing a special dance that will show after one minute slow dance. Or simply choose a song that is important for both of you (idea: if there is a slow song, search the Internet for an orchestral version or a ballad before you can use it).
