I was wondering if someone could help me create an Octane node tree that provides what a native Lightwave node tree with Ray Trace node does, which I have used to project a face on a Lego character. I want to use this method because it allows me to project a face rig that I can animate and have this rendered on to the character at the same time I render the scene. I have this rendering / working well when using the native renderer, but I want to do it with Octane..
Don't know if the camera mapping node is what I should use, but I have tried it without success. Any ideas?

Nope, Octane doesn't have any node to simulate the LW ray trace node. This could change in Octane 3 with the OSL support, but currently you can't trace a ray in the Octane scene with the available shading nodes.
I am not sure how you are using the ray trace node in your workflow, perhaps you could project your texture using an UV map. If you want to share a sample scene, perhaps somebody could find a workaround.
