Preheat Air Fryer to 390 degrees.
Cut eggplant in half. Then in 1/4 inch "slices". Cut those slices into "fry" shapes and then cut those in half.
Mix together Panko Bread Crumbs, Parmesan Cheese, Garlic Powder, Onion Powder and Salt. If possible, pulse in a food processor for a couple of seconds.
Put egg into one bowl and the Panko Mixture into another. Dip the Eggplant Fries into the egg and then coat with the Panko Mixture.
Spray Air Fryer with cooking spray and put the Eggplant Fries in. Don't layer the Eggplant. If you have a rack, you can use that. Otherwise, do them in batches.
Cook at 390 degrees for 5 minutes. Flip them and cook for another 3-4 minutes.
