Here's a snapshot of how i dealt with the finding the feynman rules if it helps at all .. this is for the πωρ vertexpic.twitter.com/4ondZ0GEEK
i imagine this method of 'factoring' would work similarly for the ωρφ vertex .. good luck, though .. i remember that references for the vector mesons in the anti-symmetric representation took a lot of digging

Is there a good way to translate between interaction vertices expressed a) in "antisymmetric tensor representation" for vector mesons to b) their "usual" vector representation? To re-express your Feynman rule for rho_mn - omega_mn - pi to the "usual" rho_m - omega_n - pi ?

i can't seem to find the reference at the moment, but there's this wonderful detailed paper that goes over it in the appendix.. for what it's worth here's how the feynman rules for the external legs are related in the two representations .. i think you can get basically.. 1/2pic.twitter.com/OABkG90U8K
