How can we work on strengthening our faith?
What are some spiritual exercises, duas, or advice we can follow to build our iman?

a sound way for the believer to keep his faith is by being strict with his personal religious duties, lenient and generous with others, and by talking often with Allah. Then, when Allah speaks to him through the Qur'an, his faith will increase insh'Allah: "and when His verses are recited to them, it increases them in faith" (8:2), "As for the believers, it [the revelation] does certainly increases their faith" (9:124).
With prayers for your success.
