Your yellow Tabebuia (Tabebuia chrysotricha or similar) lost all leaves to a freeze, then refoliated fully—but produced no flowers.
If the tree leafs out well this year, it should set flower buds for next spring—provided no another hard freeze occurs. No special treatment needed; just maintain good care.
