Slice the eggs crosswise into thin slices, reserving the top and the bottom for another use.
In a small bowl stir together the mayonnaise and the Sriracha. Set aside.
To assemble, lay out the toast and spread the spicy mayonnaise on each piece. Lay a piece of lettuce on the spicy mayonnaise. Top the lettuce with two overlapping slices of egg and a piece of bacon to finish. Serve immediately.
