Here is a link to a post in Citehr where a member has shared her PPT on employee engagement for her corporate. I am sure the suggestions given above as well the outline of possibilities in the PPT and some search in this site can help you structure something relevant and effective for your organization.
Let me also add that each engagement activity must be thoroughly studied for its relevance to your employees, its suitability to your organizational culture, the budget allocations, its implementation and its effectiveness. Employee feedback and suggestions can give you excellent insights to make the activity even more effective with some minor changes or a bit of tweaking.
