If you want a longer lasting effect and you don't have thaumaturgy, then the only solution is consequences. Of course as Tedronai has pointed out, that's a poor solution too.
Why is this a poor solution. Let's look at incite emotion:
YS P.173
If you can touch someone, you
can make him feel something.
You’re able
to do maneuvers at +2 to your roll (using
Intimidation for anger or fear and Deceit for
every other emotion) that force an emotion
on a target (as a temporary aspect), so long
as you’re in the same zone as he is and you
can physically touch him. The victim defends
with his Discipline.
You may be able to
prevent the victim from taking other actions
as well if you do this as a block (page 210)
instead of as a maneuver.
Emphasis mine. So this is exactly what people are suggesting the OP do. Use maneuvers or blocks
YS p.173
Lasting Emotion [–1]. If you increase the
refresh cost of this ability by 1, you gain the
ability to do Emotion-Touch as a mental attack
instead of a mere maneuver or block. If such
an attack hits, you gain a +2 stress bonus on a
successful hit (as though it were Weapon:2),
increasing the chances of inflicting a mental
consequence (and thus, a more lasting
emotional state). The victim defends with his
Discipline.
But wait! If the victim chooses the consequence, how does lasting emotion even work?? It works because the attack dictates the type of consequence. It dictates how the narrative should be carried out, if not the exact consequence.
