Wheat Free Tempura?

Hello! I have a wheat allergy, and it means I cannot eat many of my favorite foods :( so I am always on a mission to find good wheat free recipes! One of my favorite things is a shrimp tempura onigiri. I love them so much, and I used to eat them almost every lunch at work, but now I cannot eat them because the batter has wheat in it! Is there anyway to make tempura without wheat? Or is it just disgusting then? If you have any wheat free tempura recipes, please share! I would really appreciate it ^^ and my belly would thank you too :3 hehe
