In a 'Vegeta kidnapped' fanfiction, perhaps Vegeta could be kidnapped by an old enemy seeking revenge. This enemy might be from his Saiyan past.

He may also be worried about how his family, like Bulma and Trunks, are coping without him.
The story might center around a new threat to the Earth that only their combined efforts can defeat. Vegeta uses his fighting skills and Bulma uses her intelligence to create new gadgets or find weaknesses in the enemy. Along the way, they reaffirm their love for each other and strengthen their family unit.
The fanfiction could focus on the challenges they face during the pregnancy. For example, Bulma might have some health scares that make Vegeta worry a great deal.

It could be that Vegeta is influenced by some external force or an old Saiyan belief that makes him act in a way that hurts Trunks.

As the fanfiction progresses, Trunks could start to rebel against Vegeta's ways, and they would have to navigate through their differences and find a middle ground.
