Germany
- Ceding Alsace-Lorraine to France and perhaps demilitarisation of border region.
- Ceding some border regions on East Prussia and Silesia to Russia.
- Germany has give some of colonies, probably Togoland, Cameroon and Pacific Islands assuming that Japan still joins. But now it would get everything altough Germany might be allowed to keep German Samoa since it is pretty far from Japan.
Austria-Hungary
- Has cede Galicia to Russia.
- Ceding Bosnia to Serbia.
- If Italy jumps to the war (what I bit suspect) it gets Southern Tyrol and Istria. Perhaps Dalmatia or parts of that too. Otherwise A-H continues its existence or at least Entente doesn't forcibly dissolve that.
I’m not sure the treaty would be this lenient. The UK has little sway over the treaty signed and the French will be wanting to do as much damage to Germany as possible.
- Memel and Galicia ceded to Russia.
- Semi-independent Polish state established; Danzig corridor, Posen, upper Silesia gobbled up.
- South Tyrol, Istria and Dalmatia ceded to Italy.
- Bosnia, Croatia and Slovenia to Serbia.
- Hungary partitioned and independent Czech state established.
- Annexation of Alsace-Lorraine and Saarland by France, Eupen to Belgium, Rhineland puppet state split off.
- North Schleswig given to Denmark.
- Balkanisation of Germany, Kaiser’s son given Prussian throne, independent Bavaria and Baden, some sort of North German partition plan.
With the domineering presence of Russia I don’t see any future war occurring or another reunification of Germany—in fact, the German national project probably takes a hit due to the embarrassing fashion in which the war was lost. I suspect all the new independent German states, likely with their own monarchies, would want to avoid another united Germany too.
