Baking batter-covered chicken instead of frying?
I may be off base here, but Wondra Flour is the first thing that comes to mind.  Its’ an instant flour aka pre-cooked.  You could really cut back on the liquid in order to make a drier batter and use an egg and a little milk/water and other desired seasoning.  

Use two bowls, one for dried Wondra Flour, the second for the batter.  First toss the chicken in dried Wondra Flour, then into batter, pull out then back into dried flour. You will have to experiment a little to get the right combo, just keep in mind you can always rinse off the chicken and try again.  Using an Oil Spray Bottle spray the back then put on racked baking sheet spraying the top.  Halfway through the cooking process, you will need to turn over the chicken pieces as moisture will accumulate on the bottom.  This also works best in a convection oven.  If you are heavy on the oil spray, you are defeating the purpose of oven baking, so keep it light.  Also, you may want to cut the chicken in larger pieces to give the batter a chance to brown.  

If your supermarket doesn't carry it, just go to customer service and requested they start to carry it.  You may have to talk to a Manager, but they usually will order it in. There is always online.
