Try using shell continuation "markers " the backslash \ Also added { }
Code:
for f in $(find . -type f -name '*.mkv'); 
do 
   ffmpeg -n -y -i "${f}" -vf scale=720:-2 -c:v mpeg4 -vtag xvid -b:v 969k \
           -r 25 -pass 1 -an -f avi /dev/null && \
   ffmpeg -n -i "${f}" -c:a libmp3lame -b:a 48k \
           -ac 1 -vf scale=720:-2,subtitles="${f}.srt":force_style='Fontsize=20' \
           -c:v mpeg4 -vtag xvid -b:v 969k -r 25 -pass 2 ".${f}.avi" ; 
done

I cannot vouch for the correctness your ffmpeg commands at all. Try it.
