You can replace coriander with cilantro, which is the leafy form of the seed, coriander. This is not an exact match, and the flavor/scent of cilantro is stronger than coriander, so be very careful.
I'd replace 1tsp of dried coriander with 1/2tsp of dried cilantro or 1Tbsp of fresh, minced cilantro.
Cumin might make a reasonable replacement. Depends whether you need ground or fresh.
