Stand the cauliflower up on a cutting board and slice it in half from top to bottom. Trim off the excess stem, leaving just enough to keep the florets attached. Slice each half into thinner slices. I usually get about 3 slices per half. The further away from the center you get, the harder it is going to be to keep the florets from breaking apart. It's okay if they fall apart a bit. Cut each slice in half again from top to bottom, if you like, to make them easier to work with and a bit less delicate.
Whisk together the coconut milk, zest and juice of 1 lime and ½ teaspoon salt in a wide shallow bowl, set aside.
Whisk together the panko, cornmeal, shredded coconut, smoked paprika, cumin, garlic powder, turmeric, ½ teaspoon salt and the pepper in another wide shallow bowl, set aside.
Line up your breading station in this order: cauliflower, wet batter, dry breading, prepared baking sheet.
Take a slice of the cauliflower and place it in the coconut milk batter, flipping it over to make sure all sides are covered. Next, place that slice of cauliflower in the dry breading mix, pressing it down and flipping it over to make sure it's coated evenly on all sides. Transfer your breaded slice of cauliflower to the lined baking sheet. Repeat with all remaining slices of cauliflower. Do not overcrowd the pan. Make sure to leave space between each slice of cauliflower. Use two pans if needed. Bake the breaded cauliflower for 25 to 30 minutes, flipping each piece over after 15 minutes, until both sides are golden brown and crispy.
