Neil,
I don't know of anything standard, but lambert and albers are what
come to mind.
There are the esri-crafted albers projections for asia that do not
have epsg listings but might be useful references.
See the esri Albers options here:
http://spatialreference.org/ref/epsg/?search=GCS_North_American_1983
+albers&srtext=Search+WKT
At www.spatialreference.org you can also find these customized albers
projections that could be helpful for ideas on crafting your own:

Finally, while esri has not crafted asian lambert projections like
albers these still might be useful:

Cheers,
Dane
