How about booking him a skydiving experience for Father's Day? You could either book a tandem skydiving session, where he jumps with an instructor, or an accelerated freefall course where he jumps solo, but with instructors nearby to help guide him. If he has already experienced skydiving, you could get him skydiving gear like a new jumpsuit or helmet. Another idea is to get him a gift card to a dropzone that he can use anytime he wants to go skydiving.
Or you can get him a star map with the date when he welcomed you in this world.
