Your asking for alot.
The easy way would be a German U-boat that sinks something remotely American, have America focus solely on Germany for a bit. Pearl habour occurs, America declears war but keeps Berlin on priority, less ships are in Pearl Habour due to the focus on the Atlantic. Germany is defeated in late 1944 as the entire industrial might of America is pouring bombs on bottlenecks in the German economy. After VE day the focus is shifted to the Pacific. The Japanese control a good deal of China, Oceania, & Burma, however as with OTL they would have trouble with logistics even with less merchant loss to the USN. The USN + the Royal navy grinds with the IJN in the Pacific, by 1945 Japan is still able to defend it's airspace but it's only a matter of time until 80% of the economic strength of the world shows.
