Smith watched his team end a punishing 16-match winless run with a 1-0 victory over Colchester last weekend and they duly followed that up with a stunning 4-2 success at MK Dons on Boxing Day.
Smith kept faith with an unchanged XI for both games and, with no new injury or suspension problems expected, will likely send out the same side again at Brisbane Road.
Midfielder Florent Cuvelier will continue to build up his match fitness after increased cameos against the U's and Dons following his return from a lengthy hamstring injury.
Midfielder Nicky Featherstone (ankle) will again be assessed ahead of the clash.
Saddlers boss Smith spent six years as a player with Orient, racking up over 300 appearances, before returning as youth coach and assistant manager, eventually parting ways in 2009 before linking up with Walsall.
