Loadpdb does it automatically for residues that have templates
loaded in leap, such as the standard amber ff ones.

You need to create the template and load it. To get the initial
coordinates you could make a guess and let a qm or semiempirical
program minimize to a reasonable spot. Or use xleap to load a
pdb of the residue w/out H, set the bond types graphically, draw
in the H at a promising location, and use the leap cmd to fix
coordinates (I forget what the cmd is) using hybridization to set
the position.
