You'll need to find the source file tex-text.map (probably in your
texmf tree at fonts/misc/xetex/fontmapping/base), make a copy with a
new name, and add the mapping rules you want, following the pattern of
those already there. Then use the tool teckit_compile to compile this
into a binary .tec file that xetex can use. Install this in your
personal texmf tree under fonts/misc/, similarly to the standard
mapping provided with the distribution, and load it with the
Mapping=.... option of fontspec.
(The mappings are handled by the TECkit system; see http://scripts.sil.org/teckit
for more detail.)
