The preexec from Eivind Uggedal works great with a tmux session that uses the default tmux socket. Here's an enhancement that works with any tmux socket:

function preexec() {
  if [[ -n $TMUX ]]; then
      TMUX_SOCK=$(echo $TMUX|cut -d , -f 1)
      NEW_SSH_AUTH_SOCK=$(tmux -S $TMUX_SOCK showenv|grep ^SSH_AUTH_SOCK|cut -d = -f 2)
      if [[ -n $NEW_SSH_AUTH_SOCK ]] && [[ -S $NEW_SSH_AUTH_SOCK ]]; then
          SSH_AUTH_SOCK=$NEW_SSH_AUTH_SOCK
      fi
  fi
}

I think you're mistaken, it works flawlessly here on reattachment of a tmux session. Look up update-environment in tmux's manpage to see why it works.

It does look like there is a much more simple solution for just tmux with showenv/setenv, but I don't think it's this. The above will just replace SSH_AUTH_SOCK with what it is set to already.

A much simpler solution for tmux is to put this inside your .zshrc:

function preexec() {
  if [[ -n $TMUX ]]; then
    NEW_SSH_AUTH_SOCK=`tmux showenv|grep ^SSH_AUTH_SOCK|cut -d = -f 2`
    if [[ -n $NEW_SSH_AUTH_SOCK ]] && [[ -S $NEW_SSH_AUTH_SOCK ]]; then
      SSH_AUTH_SOCK=$NEW_SSH_AUTH_SOCK
    fi
  fi
}
