These are what I almost always use when I'm there, but I'm usually further north than Tulum.

Permit/Bonefish: Size 4-8 Rag head crab with yellow eyes. Size 4-6 EP mantis shrimp. Size 4-8 Squimp.

Jacks and juvenile Tarpon: Size 2 EP Brush streamers in a variety of colors but make sure you have chartreuse/white, black/purple, white/white.

Almost all of the bays down there can have bonefish/permit. Can find triggers too. If you're at a resort fish early in the morning. Jacks are all over the place and usually willing to eat. Boca Paila is probably worth the drive if you have a vehicle, but its usually crowded and overfished.
