Preheat the oven to 425°F. Line a baking sheet with parchment paper.
In a large bowl, toss the zucchini slices with salt and let them sit for about 10 minutes to draw out moisture. Pat the zucchini dry with paper towels.
In a separate bowl, mix together the garlic powder, onion powder, paprika, black pepper, breadcrumbs, and Parmesan cheese.
Dip each zucchini slice into the beaten eggs, allowing any excess to drip off, then coat it with the breadcrumb mixture, pressing gently to adhere.
Arrange the coated zucchini slices in a single layer on the prepared baking sheet. Lightly spray or drizzle with olive oil.
Bake for 20-25 minutes, flipping halfway through, until the chips are golden brown and crispy.
Let the zucchini chips cool for a few minutes before serving.
