TeX output via TeXForm: variable name translation

I am trying to find a good way to interoperate between Mathematica and
LaTeX (or LyX).
Typically, I am workign with multi-character variable names, which
TeXForm interprets as text:
In[65]:= TeXForm[e1]
Out[65]//TeXForm=
\text{e1}
To get around this, I am trying to create a translation table of
sorts: e.g.
TranslationTable1 = {{e1, "\\epsilon_1"}, {e0, "\\epsilon_0"}, {kz0t,
"\\tilde{k^{(0)}_z}"}, {kz1t, "\\tilde{k^{(1)}_z}"}};
I would like, if possible, to perform those replacements in
Mathematica, without writing and invoking external scripts. The first
thing I tried was this:
TeXReplacements := (Rule[#[[1]], ToExpression[#[[2]], TeXForm,
HoldForm]] & /@ TranslationTable1)
In[67]:= (e1*kz0t) /. TeXReplacements // TeXForm
Out[67]//TeXForm=
\epsilon _1 \tilde{k_z^0}
(This simply does the following:
In[69]:= (e1*kz0t) /. {e1 -> ToExpression["\\epsilon_1", TeXForm,
HoldForm],
kz0t -> ToExpression["\\tilde{k^{(0)}_z}", TeXForm, HoldForm]} //
TeXForm
Out[69]//TeXForm=
\epsilon _1 \tilde{k_z^0}
)
Notice how this doesn't work: Take a look at the translation table
above and notice parentheses around in k_z^{(0)}. Mathematica
discards these parentheses.
So the question to the group is: (1) is it possible to preserve the
formatting exactly how I specified it in the translation table before
converting to TeXForm or (2) is it possible to do a replacement using
my translation table after I had converted to TeXForm or (3) is there
a better solution altogether?
Thanks!
