All you need to do is replace zsh provided format strings to that of
similar  bash escape sequences.  For example, zsh '%n' (for
username) corresponds to bash '\u', '%~' to '\w', and so on.

I personally put the color, bold, normal, etc. sequences in a
separate file, which is sourced inside the file setting prompt.
That gives less of gobbledygook to parse.  For zsh, i have somewhere
in ~/.zshrc ...

  #  http://www103.pair.com/parv/comp/unix/cf/sh/var/colors
  . ~/cf/sh/var/colors

  case $TERM in
    *xterm* | *rxvt* )
      PS1="# ?:%? %j %l ${bold}${yellow_fg}%~${normal}${normal}"
      PS1="$PS1 %n.${bold}${cyan_fg}%m${normal}${normal}"
      PS1="
  $PS1 (%D{%a %b%d %I%M})
  #! "
      export PS1
    ;;

    * )
      PS1="# %j %n@%m %l ${bold}%3~${normal}
  # "
      export PS1
    ;;
  esac


... similar thing is done for bash prompt.
