One plot idea could be that they initially struggle with the news. Zuko might be worried about how his role as a leader would be affected while Mai is dealing with the physical and emotional changes. They could face challenges from the Fire Nation's traditional views on pregnancy and family. Another idea is that they go on a journey to find a safe place for their child to be born, away from the political unrest in the Fire Nation.
Well, perhaps in the fanfiction, Zuko and Mai's pregnancy could be a catalyst for change in the Fire Nation. Their unborn child represents hope for a new future. They might start initiatives to improve the lives of expecting mothers in the Fire Nation. And also, there could be a sub - plot where they have to protect Mai from those who might see the unborn heir as a threat.
A possible plot could involve Zuko and Mai preparing for the baby's arrival. Zuko could be shown learning about parenting from his own experiences or from others. Mai, on the other hand, might be exploring her new role as a mother - to - be. There could be cute moments like Zuko trying to build a nursery or Mai shopping for baby clothes, all while dealing with the expectations of the Fire Nation court.
One possible plot could be that Zuko and Mai are initially shocked by the pregnancy. They then start to prepare for the baby's arrival. Zuko might be a bit overprotective, while Mai tries to keep her cool. Their friends could be excited or worried, and there could be challenges like dealing with the public's reaction as they are important figures. Maybe they face some threats to the unborn child which they have to overcome together.

Along the way, he realizes just how much Mai means to him. Or a story where Zuko and Mai are forced into an arranged marriage by Fire Nation politics.

Since Zuko is Fire Lord, Mai would have to support him in diplomatic matters, and they might face opposition from some traditionalists. Another plot could be about their family life, like how they raise their children to understand the importance of both power and compassion. Also, a plot where they have to defend their relationship against external threats, such as an old enemy trying to drive a wedge between them.
A plot twist could be that an enemy from their past resurfaces because they hear about the pregnancy. This enemy wants to use the unborn baby for some malicious purpose, perhaps as a bargaining chip or to gain some sort of power. Naru and Mai then have to go into hiding and protect themselves and the unborn child while also trying to figure out the enemy's motives and how to stop them.
Zuko's personality could be shown as more tender and caring than ever. He might be constantly worried about Mai's well - being and that of the baby. His sense of responsibility would be heightened. Mai, on the other hand, while still maintaining her dry sense of humor, would show a more vulnerable side. She may not be as openly emotional as Zuko but her actions, like making sure the nursery is safe, would show her love and care for the unborn child.

One plotline could be the challenges they face in the Fire Nation. Since Zuko is the Fire Lord, there might be political implications of his partner being pregnant. People might try to use the situation to their advantage or there could be concerns about the safety of the unborn child.
In a fanfiction, Zuko and Mai's relationship could be filled with lots of unspoken understanding. Zuko, with his intense and often brooding nature, would find solace in Mai's calm and collected demeanor. Mai, who has always been somewhat of an outsider in her own way, would see Zuko as someone who truly sees her. Their relationship might develop as they engage in activities together, such as training sessions or diplomatic meetings. Zuko could start to rely on Mai's sharp observations and insights, and Mai would find herself falling more in love with Zuko as she witnesses his growth and determination to make the Fire Nation a better place.
