From the details that you have provided, it appears that you are infected with Hepatitis B virus which is in the non-replicative stage.
As your wife is HBsAg negative, there is a potential risk of the virus being transmitted to her. The risk however is low as you are HBeAg negative. However, your wife should be fully vaccinated before you can plan for unprotected sex/conceiving baby. For this she should receive three doses of hepatitis B vaccine at intervals of 0, 1 and six months. One can also confirm the vaccinated status of your wife by doing Anti-HBs levels after three doses, which however is not a must. But she does not need hepatitis B immunoglobulin for her protection.
I will be glad to answer any further queries that you may have regarding hepatitis B infection.
