Take your and his friends to a minor league or college game. Often they'll announce the birthday and have special gifts. Or have some college athletes provide coaching for you son and his friends. Go-kart racing would be fun. An indoor game arcade is another good option.
Take him camping, or to an amusement park, or to the beach, or to a summer camp. Make sure he has family and friends. Or take him to the circus, to the mall, or to a funny museum. Your spiritual leader can help in putting a religious perspective into his birthday.
Kids enjoy places with alot of action, excitement, pizza, and video games. Family Fun Centers are great as they often offer go-karts and other outdoor action rides. Be sure that the facility has a wide array of video games available.
I would suggest either an arcade or an outdoor amusement area. Most big cities have some sort of food/arcade gaming arena, and those are always fun with the kids. Another idea could be a laser tag place. Boys enjoy that kind of thing.
