I have a plugin which uses lots of functions which are deprecated now.
Since the macro GIMP_DEPRECATED_FOR suggests functions with totally  
different parameters

(gimp_drawable_get_buffer has a single drawable_ID parameter only)

is there a recipe how to translate the old calls into the current  
function calls?


first of all, there should clearly be a guide for porting
GimpDrawable/GimpPixelRgn code to GeglBuffer.

gimp_drawable_get_buffer() or gimp_drawable_get_shadow_buffer()
are the right replacement APIs here. What to do further depends
on what you do next with the pixel region. Look at the
GIMP_DEPRECATED_FOR() above the remaining pixel region functions
to figure how to proceed with the buffer.

The GEGL API is documented at

Maybe you can write up a tutorial about how you ported
your plug-in :)
