It is well known that light has a dual nature. However, the energy and momentum conservation equations embody the wave aspect of light but not the material aspect of the photon. Should there be additional terms reflecting this aspect of the photon as in the photoelectric and Compton effect?

Classical electromagentic waves and photons are two ways of modeling the same phenomena. The momentum carried by a beam of light is not "wave momentum" plus "particle momentum", it's just the one momentum that can be described either way.
For certain observable phenomena it is clearer to chose one description than the other, but this is a choice of how to describe the thing not a selection of a subset.
