in addition to what Aliaksandr wrote,
there is also the FeynRule function which doesn't require Phi
Furthermore, FeynArts has a ModelMaker routine (see chap 7.5 of
that is supposed to be able to generate
Feynman rules from the given Lagrangian. That is probably the most
useful tool to use if you want to evaluate the resulting diagrams
