For what it is worth..I have kept a prayer journal daily now for over 30 years. Sometimes I change the format..and write down something which comes to mind during the day or a scripture I want to remember, a prayer need someone shares, etc..but to keep on track I usually use this little approach using the key letters: CHRIST..(easy to remember and simple)
CH....Cleanse my heart, Lord, that I can pray aright. (I ask God to cleanse my heart so I can rightly hear from Him and discern rightly) remembering that the prayers of the righteous availeth much.
R..I revoke any wrongful thoughts that may try to come in and interfere with my prayer time with the Lord always doing this in the powerful Name of Jesus.
I..I invite the Holy Spirit to be present in me and guide me in my prayer time.
S..I ask the Spirit to lead me to scriptures from the Word which are relevant to any prayers I say. (This can take searching the bible passages or may just easily pop into my thoughts)..or one of the ones I wrote down earlier. )
T..(very important) I thank God in advance for anything He wants me to pray and actually ask Him to direct me in what I pray and who I pray for if interceding for others.
Hope this helps. Not to be rigid but flexible..that is the key. Also believing that God, the Holy Spirit will be present and help us pray.
And, it goes without saying, that I write these things down including scriptures and prayers said..dating this every time I put an entry in my journal. (It also helps to backtrack months later and see what God was doing at the time of that journal entry)..sort of looking back on God's footsteps in my life.
peace and blessings..
