A long time ago, when I wrote my sub-package PHI I tried to fill this exact gap by providing some simple examples both from chiral perturbation theory (which PHI was written for originally), but also from QED. You can find them by clicking on the "PHI" link on the front page and then looking in the "Examples" directory. There's som html at e.g.
The idea of PHI was to allow a lagrangian as starting point and then have FeynCalc/PHI generate the necessary Feynman rules for FeynArts automatically.
Of course this was done so long ago that I doubt it'll work with the current version of FeynArts. It should be pretty straight forward to fix though - for anyone interested enough :-)
