Bash: how to check if directory exists and that it has files in it

I want to print out all sub-directory names with their content file names below the directory name. If a sub-directory is empty then don't print the directory name and go to the next sub-directory. The applicable part of my code:

for dirs in "$mydir"/*
do
   if [ -d "$dirs" -type f" ] && [ "find "$dirs" -type f" ]
   then
      echo "Processing directory $dirs"
         for subfiles in $dirs/*
         do
            echo "Encoding $subfiles"
         done
   fi
done

If I leave off the second condition of the first if statement then empty directories will print their name to screen and a * will be listed below that (I guess representing the fact that there's nothing in the directory). The portion after the && doesn't cause any errors, but it isn't preventing empty directories from seeing the rest of this section of the code.

How can I get this to work?
