Clay began her acting credits with the role of Raven Alexander on the soap opera The Edge of Night. She did two television movies before being featured in the BRit25C episode "Vegas in Space", in which she (as Maj. Marla Landers) accompanies Buck to a pleasure planet. Erin Gray only appears briefly in the episode, so perhaps they were throwing their number-two choice for Wilma Deering a bone?
Clay's feature film roles were as Amy Striker in The Legend of the Lone Ranger (William A. Fraker, 1981) and as Pat Healy in WarGames (John Badham, 1983). Aside from these she did several other television films and guest appearances on shows [IMDb].
Sadly, I am only familiar with Clay from the "Vegas in Space" episode of Buck Rogers, but it is clear that she would have handled the role of Wilma Deering nicely. The Marla Landers character is very much like Wilma Deering in behavior and attitude, and Clay's performance is a series standout. I love Buck Rogers, but let's face it, there was quite the stream of bad actors in there.
Clay died in 1995. The cause of death seems to have not been released, as the IMDb claims she died of a "heart ailment" and Wikipedia contends it was from breast cancer.
