Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Set up a breading station with flour in one dish, beaten eggs in another, and a mixture of panko breadcrumbs, Parmesan cheese, garlic powder, oregano, black pepper, and salt in a third dish.
Coat each eggplant round in flour, shaking off excess.
Dip the floured eggplant slice into the beaten eggs, allowing excess to drip off.
Press the eggplant into the breadcrumb mixture, ensuring it is well-coated. Repeat for all slices.
Arrange the coated eggplant rounds on the baking sheet in a single layer and drizzle with olive oil or spray with olive oil.
Bake in the preheated oven for 20-25 minutes, turning halfway through.
Allow to cool slightly after baking to firm up the crust.
