Tofu can be made 3 or 4 days in advance and stored in fridge.
Wrap a block of extra firm tofu in some paper towelling or a clean kitchen towel. Place a couple heavy books or a cast iron skillet on top to press for about 5-15 minutes.
*While the tofu is pressing make the dragon sauce.
Cut the tofu block into ~1" cubes and place back on paper towel.
Dust tofu cubes with liberal amounts of cracked black pepper and finely ground pepper - pressing pepper into all sides. Add a sprinkle of garlic powder (or any spice) over the cubes.
Heat oil in a cast iron pan (or oven safe skillet) on high heat until shimmering, sprinkle with sea salt.
Sear the tofu on each side until golden and crispy. The tofu will naturally release from the pan as it crisps up.
Oil-free Tip: Place the tofu in the hot non-stick pan (medium-high) and don't touch it until the tofu naturally releases. Then flip to sear on all the sides.
