PSF files aren't the only way of specifying bonds, just a convenient
one. I'm unfamiliar with VASP or how bonds are specified there, but in
principle you could specify all the bonds manually and write out a new
psf file for the structure. There is a command to explicitly set a
complete bondlist, but its a pain to use (see the atomselect interface).
A friendlier interface is found in topotools
(http://www.ks.uiuc.edu/Research/vmd/plugins/topotools/), which can be
used to add individual bonds between atomic indices. Once you've built
this internal datastructure once, you'd write it to a psf or other
structure-containing file. In a psf specifically, these would show up
under the BONDS heading.
