Using a meat tenderizing tool, pound both sides of each steak.
In a large bowl, whisk together the buttermilk and egg.
In another large bowl, mix together the flour, cornstarch, baking powder, paprika, black pepper, garlic powder, salt, oregano, and cayenne pepper. Mix in 3 tablespoons of the buttermilk mixture with a fork, making the dry mixture slightly crumbly.
Dip each steak in the buttermilk & egg, making sure evenly coated, and let the excess drip off. Then dredge the steaks in the seasoned flour mixture, thoroughly coating each.
Pour the canola oil into your large skillet or wok, and heat on your stovetop at medium-high. Let oil come to temperature (should reach approx. 425 degrees).
Gently shake each steak to remove any excess flour, and place them into the skillet. Reduce heat to medium and fry for about 4-5 minutes, then carefully flip and fry for 4-5 more minutes. Each side should be golden brown.
