Here's what the latex preamble looks like for my PDFs:

\documentclass[11pt,a5paper,openany,oneside]{book}
\usepackage[a5paper]{geometry}
\usepackage[pdftex,pdftitle={The Title Goes Here},pdfauthor={Last_name, First_name}]{hyperref}
\usepackage[pdftex]{color,graphicx}
\usepackage{mathpazo}

\textwidth 128mm
\topmargin -15mm
\textheight 175mm
\evensidemargin -15mm
\oddsidemargin -15mm

Here's the script I use to convert the latex to HTML (using latex2html):

#!/bin/sh
# Pass in the name of the top-level TeX file, or "main.tex"
# will be assumed.

if test $# -eq 0
  then
    SOURCE=main.tex
  else
    SOURCE="$1"
fi

latex2html -nonavigation -nobottom_navigation -noaddress -noinfo -math -math_parsing -accent_images 'large' "$SOURCE"

cd `basename "$SOURCE" .tex`
fontresize.sh

The fontresize.sh script looks like this:

#!/bin/sh
for i in *.html
do
        sed -e 's/+2/+0/' < $i > j.j
        mv j.j $i
done

After that is done, I import the HTML files to the Sigil program to create the EPUB. This step is a bit tedious, so maybe there's a better way to do it (perhaps with calibre?).
