I know that you can triangulate a selected portion of a mesh in Edit Mode by hitting CtrlT. This converts all quads and n-gons into tris. How how can this be reversed, combining coplanar triangles into quads and n-gons?

You can use the decimate modifier using the planar option and apply it. decimate modifier

This also turns them to n-gons while Alt J does not. Note that it likely won't work to set the Angle Limit to 0. –  Keavon Jul 3 at 14:44
    
Note that this is the same as Limited dissolve in edit mode. –  gandalf3 Jul 3 at 19:49

You can untriangulate the selected portion of a mesh by hitting AltJ. This will only create quads so some manual cleanup may be necessary if you need n-gons. You can do this by selecting the leftover edges and hitting X and clicking Dissolve Edges.
