Clean the squash and slice it between 1/8 and 1/4 inch thick. If using a slicer, aim for about 1/8 inch.
Toss the sliced squash with 2 tablespoons flour until lightly coated.
Whisk together the buttermilk and egg, pour it over the squash, and toss until all of the slices are coated.
In a separate bowl, combine the cornmeal, 6 tablespoons flour, salt, black pepper, garlic powder, and paprika.
For extra crispy bits, toss about 1/4 of the breading mixture into the bowl with the wet-coated squash to create small clumps.
Coat each squash slice in the remaining breading and place on parchment paper or another nonstick surface.
Heat enough vegetable oil to completely submerge the squash to 350°F.
Fry the squash in batches without overcrowding the oil for about 3 minutes, or until golden brown.
Allow the oil to return to 350°F between batches.
Transfer the fried squash to paper towels or a wire rack to drain. Serve warm.
