Something like this?

  tar --create --file=- --directory=/dir1 ./ | gzip -c |
    curl -T- tftp://192.168.20.10/gzipimage.tar.gz

The -T option can read the uploaded file from stdin when '-' is used. But when
so, it has no file name to append to the URL so you better set the full name
in the URL you're uploading to.
