D-serine is trivial: take L-serine and swap the improper on the Ca.

Build yourself 'by analogy', i.e. by looking at similar parts of other
building blocks. Or use the ProDrg webserver, which usually does a good
job in automating this arduous task. You do want to check the generated
topology carefully (as you would for any generated topology), and if
you want the Gromos or OPLS forcefields, you will have to translate it
afterwards (ProDrg only generates Gromacs ff topologies).
If all you have is C, N, H, O and some P or S, it shouldn't be too hard...
