Smoke has pretty much no recovery on his jump kick if you hit somebody in their shin or foot with it. This means you can combo off of it anywhere on the screen if your spacing is correct. I'm pretty sure it's a universal property but smoke can really abuse it. This also works when crossing people up, should you be able to actually make that happen
DEEEEEEEP jik > full dash > d1 xx bomb > max height 32 > half dash 3d12 > uppercut. 35%
You can vary your juggle to suit your needs, obviously. This is the most damaging version that I've found, while ending with a 2 xx smoke bomb will do 1% less, be more consistent, and lend itself to oki in the same way that the uppercut would.
What happens if it gets blocked? Well congrats, you've basically just done a JIP. You have at least 10 frames of advantage here, maybe more, put that betch into pressure.
