Element type with 'baked-in' fields

Question

I've created an element type and want to have a 'Categories' and 'Tags' field built-in (the sources for each will be selectable in settings), but can't figure out the best way to go about this whilst supporting custom field layouts with tabs.

Do I just hard-code these fields into the edit page/hud html code then handle the logic on the save controller (this is fiddly whilst keeping it customisable/tab-able), or is there a better way to do it? I.e inject them into the field layout via the controller?

Can't get my head around this one.

I've given up on this, from what I've looked at it's not going to be easy without a migration that creates the fields first (don't really want to do this for updatability issues). I've changed the scope of the plugin to be more bare-bones, and I think it's better for it.
