Not really, catseye. Not for me, anyway. The methods are entirely distinct in terms of purpose and framing. Prayer is a process that is framed, even delineated, by formally approved doctrinal authority. It takes the form of mental or verbalised petition, intercession or some other liturgical goal. Most distinctive of all, the fundamental difference is the direction - in christian prayer, a single supernatural deity is petitioned, and generally in terms the religious authority rules appropriate.
Magical practice can focus on anything that the practitioner identifies with in a meaningful way. Also,magic often employs complex material technology to create a receptive environment for the processing of the rite. If one thing doesn't come off effective, adjust, eject or replace.
Those are just a few everyday examples from an individual perspective. I'm not going into the more organised group or grimoiric processes coz I know nothing at all about it. I perceive there would be more distinction the deeper you go with either practice.
