IMHO a fair treaty would have been something along these lines:
-Reparations limited to the damages caused by Germany to Belgium + France
-Cession of Alsace-Lorraine to France and Malmedy (but not Eupen or St. Vith) to Belgium
-Plebiscite between Germany and Luxemburg in the (tiny) areas lost by Luxemburg to Prussia in 1815 (if France and Belgium get something, why shouldn't Luxemburg, they were invaded as well)
-Plebiscites in Memel, Posen, West Prussia, Upper Silesia, Mazuria, which Germany would probably win except the Posen one
-Free access for Poland to the ports of Memel, Königsberg, Danzig and Stettin if Poland does not win the West Prussia plebiscite (Czechoslovakia got something similar in OTL regarding Stettin and Hamburg). Extraterritorial road and railroad to East Prussia if Germany loses the West Prussia plebiscite.
-Nothing regarding North Schleswig since Denmark was neutral and deserves no spoils for a war they did not take part in
-Loss of German colonies
-No war guilt clause
-Not keeping Austria from uniting with Germany if the population of Austria (including the Sudetenland) so desires. This would also have the side effect of strengthening the Centre Party and weakening the Junkers later on.
-Demilitarization of the Rhineland limited to the time Germany has to pay the reparations (this would serve as an incentive to Germany to pay them a.s.a.p.)
-Saar stays a regular part of Germany, just gets occupied until France has its mines back running
-German army and navy are allowed to have 3/4 the strength of Italy, which was the weakest Entente power as far as I know. This should be sufficient not having to fear the likes of Poland. Additionally Germany is allowed to posess an air force and tanks.
-Germany is prohibited to have any diplomatic relations with the Red Russian government before the first Entente power has
