With vared, you should be able to configure a function that does
completion for your script by declaring it with zle -C:

zle -C complete-word complete-word _complete
bindkey '^I' complete-word

Looking at a script I have that does this, my _complete function starts

_complete() {
  [[ "$compstate[insert]" = tab* ]] &&
      compstate[insert]="${compstate[insert]//tab /}"

I think this ensures that it does completion rather than inserting a tab
character in some cases.

You may need other tweaking, much of which may involve copying from your
.zshrc to, for example, setup menu completion as you like it loading the
complist module and so on.

The completion functions may also look a bit different to normal
completion functions if you do things like descriptions manually, e.g.
  compadd -X '%Bnames%b'
