I use the following in my .zshrc

function precmd
{
  if jobs % >& /dev/null; then
    psvar=("*")
  else
    psvar=("")
  fi
}

PS1="%~ %!%1v> "

The precmd function is executed before printing a prompt. It checks
whether there are background jobs or not.
The %1v pattern in PS1 means to print the first element of the array
psvar.  If there background jobs, an asterisk is printed. Otherwise, an
empty string is printed.

It works fine for me.

You would just have to modify the precmd to check whether the jobs are
running or suspended and set psvar accordingly.
