Are posted logs raw events? Is there some settings in your sourcetype (props.conf) that prevents automatic extraction of the fields you wanted? Because the field names and values are connected by equal sign, Splunk should have already extracted them.
Here is an emulation of your samples:
| makeresults
| fields - _time
| eval data = split("[12/12/21] 12:10:112 GMT] I6789HIOO applicattion authenticationid=100| |35467577889999| |67775-ghhgfrt-6788h-7667788; clientid=\"7689-jhgg-8765r-kkjggt\"; app=\" \"; QueryLetter=\"yard=MS&identification=MLAS&timeRange=EVERYDAY&timePeriod=MINUTES

These are the fields extracted:
