Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
Set up a breading station: In one shallow bowl, place the flour and season with salt and pepper. In another bowl, whisk the eggs until beaten. In a third bowl, mix together the breadcrumbs, Parmesan cheese, garlic powder, oregano, smoked paprika, and a pinch of salt.
Dip each eggplant slice into the flour, shaking off excess, then into the beaten eggs, and finally coat with the breadcrumb mixture. Press gently to ensure the crumbs adhere well.
Arrange the breaded eggplant slices on the prepared baking sheet in a single layer. Spray the tops lightly with olive oil spray for extra crispiness.
Bake in the preheated oven for about 25-30 minutes, turning halfway through, until the eggplant is golden brown and crispy.
Once baked, remove from the oven and let cool slightly before serving.
