You'll want what we call a grinder pump (capable of pumping solids). It's used when you have to pump a toilet as well as a shower and lav.
Plan on supplying a separate elect. circuit to the pump and a 2" vent that will tie into your existing vent system, or if required, vent through the roof.
The pump will be sized by how high you need to lift the waste before it ties into your building drain. Yours appears to be about 6'.
You will plumb your new fixtures as normal, including vents. Then run the under slab sub drain to the pump basin. From there, the pump will lift it to your existing building drain.
