Assuming his body was found—and removed from the battlefield, your soldier was probably interred at Oakwood Cemetery in Richmond. Between January and September 1862, almost 5,000 soldiers were buried there.

The “Oakwood Cemetery, Register of Interments in Confederate Plots, Reel 121” is at the Virginia State Library.

According to http://home.earthlink.net/~oakwood_cemetery/history.html
“By war's end the Confederate section of Oakwood Cemetery covered approximately 7.5 acres and contained more than 16,000 dead. Some had been individual burials, while others were buried in groups in trenches. Most graves were marked by wooden boards, but a few had marble or granite slabs. The cemetery staff compiled a burial register containing the last name and first name and middle initial of the deceased; his rank is above private; company, regiment, and state; the grave number, row, and division; and "remarks," including (rarely) dates of death or interment and when marked by marble or granite slabs.”
