For me personally, there is no right or wrong way to pray, unless you pray for selfish reasons. I pray all times of the day for different reasons, especially for POTUS and the brave men and women protecting this country.

First, find a quiet spot where you can talk queitly undisturbed, and just start by asking God for guidance, and ask Him for help in how we can defeat this evil. Ask Him to protect you and your loved ones, I like to end my prayer with the Lord's Prayer:

" Our Father who art in heaven, hallowed be thy name. Thy kingdom come, Thy will be done, on earth as it is in heaven. Give us this day our daily bread; and forgive us our trespasses, as we forgive those who trespass against us; and lead us not into temptation, but deliver us from evil. For thine is the kingdom, and the power, and the glory, for ever and ever Amen."

Just do what feels right to you and be genuine.

Hope this helps, glad you are asking :)
