Baking lighting information into an object texture

I am trying to bake the Shading, lighting and texturing and save it to a single texture map.
(In a similar process as the Arnold render would do: https://support.solidangle.com/display/AFMUG/Render+Selection+to+Texture)

I did some research and all I can find are some really old scripts and approaches.
Can anyone point me in the right direction please?

Thanks

Christian
